Definitions
- boreholes are drilled to access hydrocarbon bearing formations for the purpose of extracting target fluids be the fluid gas, oil or a combination of fluids. While traditionally boreholes were drilled substantially vertically and therefore orientation of a bottom hole assembly could be relatively accurately tracked by tracking the orientation of the string at the surface, orientation in highly deviated or horizontal wells that are more common today is difficult and accuracy is limited. This is due in part to the frictional factors encountered as a string of several thousand feet is driven into the low side borehole wall. Because it is difficult to measure the friction all the way up the string, it is difficult to resolve the forces that act on the string and affect actual orientation downhole relative to apparent orientation at the surface.

Abstract
Description
- In the hydrocarbon recovery industry boreholes are drilled to access hydrocarbon bearing formations for the purpose of extracting target fluids be the fluid gas, oil or a combination of fluids. While traditionally boreholes were drilled substantially vertically and therefore orientation of a bottom hole assembly could be relatively accurately tracked by tracking the orientation of the string at the surface, orientation in highly deviated or horizontal wells that are more common today is difficult and accuracy is limited. This is due in part to the frictional factors encountered as a string of several thousand feet is driven into the low side borehole wall. Because it is difficult to measure the friction all the way up the string, it is difficult to resolve the forces that act on the string and affect actual orientation downhole relative to apparent orientation at the surface.
- Being able to accurately determine orientation in the downhole environment facilitates many operational interests. Therefore, the art is always receptive to new methods and apparatus that improve or enable orientation in the downhole environment.
- A pressure orienting swivel arrangement including a weight assembly and a pin adapter reactably interengagable with the weight assembly to orient the pin adapter to the weight assembly.
- A pressure orienting swivel arrangement including a housing, a spring compression mandrel within the housing, a spring disposed about the spring compression mandrel, a weight assembly rotatably supported in the housing, and a pin adaptor rotatably supported within the housing and reactably interengagable with the weight assembly to accept a torque from the weight assembly.
- A method for orienting a downhole tool including gravitationally orienting a weight assembly, interengaging a pin adapter and inducing rotation in the pin adapter with the weight assembly.
- Referring now to the drawings wherein like elements are numbered alike in the several Figures:
-
FIG. 1 is a cross section view of one embodiment of a pressure orienting swivel arrangement in a non-actuated position; -
FIG. 2 is a cross section view of one embodiment of a pressure orienting swivel arrangement in an actuated position; -
FIG. 3 is a perspective view of a weight assembly of the arrangement; -
FIG. 4 is a perspective view of a gear ring of the arrangement; -
FIG. 5 is a perspective view of a pin adaptor of the arrangement. - Referring to
FIGS. 1 and 2 , a non-actuated position and an actuated position, respectively, of one embodiment of a Pressure OrientingSwivel arrangement 10 is illustrated. A comparison of the locations of various component of the arrangement in the two figures will provide an overview for the following description of the individual components and their interactions. - Referring to
FIG. 1 , and beginning at an uphole end of the arrangement (left side of the figure as per convention) atop sub 12 can be seen.Top sub 12 is fixedly attached to aspring housing 14 at a threadedconnection 16. Thetop sub 12 includes aninside surface 18 that defines the outer most region of afluid pathway 20 through which pressurization fluid is applied to thearrangement 10 when actuation thereof is desired. Further thetop sub 12 includes aseal recess 22 receptive to a seal such as an o-ring (not specifically depicted due to scale, and not needed due to knowledge in the art). Slidably disposed within theinside surface 18 is aseal sleeve 24. - The
seal sleeve 24 is attached at a downhole end thereof to aspring compression mandrel 26 at aninterconnection point 28. Theseal sleeve 24 provides aspring shoulder 30 upon which anuphole end 32 of aspring 34 bears during actuation of thearrangement 10. Adownhole end 36 of thespring 34 bears against a bushing 38 or other surface capable of supporting thespring 34 when under compression during actuation of the arrangement. - Adjacent the
bushing 38 and through thespring housing 14 is one or more fluid displacement pathway(s) 40 (two shown) within each of which is afilter material 42 in one embodiment of thearrangement 10. This provision allows for fluid to move into or out of the arrangement while the arrangement is being actuated or released from the actuated position to avoid the potential for hydraulic locking or inhibition of movement of the components of thearrangement 10 due to hydraulic forces created by fluid in the arrangement. - Downhole of the
spring housing 14 and fixedly attached thereto is anextension sleeve 44. The extension sleeve supports apin 48 fitted to rotationally constrain agear ring 72. Within theextension sleeve 44, aweight assembly 50 is supported on thespring compression mandrel 26 atbearing 46 and bearing 52. Between thebearings arrangement 10. This is a useful attribute for the arrangement because it facilitates the self-orientation of theweight assembly 50. Orientation of theweight assembly 50 is important to the function of thearrangement 10. Further the construction of theweight assembly 50 facilitates operation of thearrangement 10. Referring toFIG. 3 , an enlarged view of theweight assembly 50 is provided for clarity of its construction. The weight assembly comprises acage 52, aweight 54, akey 56 and anorientation torque producer 58. It will be appreciated from the figure that theweight 54 extends, in this embodiment, about one half of thecage 52. The purpose of the weight is to cause that theweight assembly 50 orient itself to gravity. In a horizontal or highly deviated well, this ensures that an operator can count on a correct orientation of at least one component in the wellbore. Because the orientation of theweight assembly 50 is known, a desired orientation of another component of thearrangement 10 can be set using theweight assembly 50 as the known. The weight assembly rotates itself only and therefore does not suffer from the drawbacks of prior art devices that have attempted to use an offset weight to orient target tools. Rather the weight assembly as disclosed herein has an overall mass that is substantially concentrated in theweight 54 and therefore only a very small percentage in thecage 52 andkey 56. - Importantly then the weight assembly also features an
orientation torque producer 58 that functions to orient another component of thearrangement 10 to theweight assembly 50. It is this function that allows an operator to set a desired orientation of this separate component. The component is apin adapter 70 identified inFIGS. 1 , 2 and 5. Because the weight assembly will find gravity and the pin adapter will orient to the weight assembly, a specifically positioned tool attached to thepin adapter 70 will have a known orientation when the arrangement is actuated. - Referring for a moment back to
FIGS. 1 and 2 , further components of thearrangement 10 are identified to improve clarity of the discussion regarding the actuation of the arrangement. Agear ring 72 is positioned at a downhole end ofextension sleeve 44 and is pinned in place rotationally bypin 48. Reference toFIG. 4 makes clear the construction ofgear ring 72 including a plurality ofgear teeth 74 and lead inramps 76 to help facilitate engagement therewith by thekey 56 to prevent rotational movement of the weight assembly when that assembly is engaged with thegear ring 72. Prevention of rotational movement of the weight assembly means that all of the torque production capability of theorientation torque producer 58, in this embodiment a helical profile, is available to turn thepin adapter 70. The pin adapter rotates within apin adapter housing 78 which itself is joined to theextension sleeve 44 by astop sleeve 80. Thepin adapter 70, in this embodiment is supported within thehousing 78 by a radial type bearing 82 and a thrust bearing 84. Aseal 86 is provided between thepin adapter 70 and thespring compression mandrel 26 to seal the arrangement and working withseal 22 for pressure based operation. - At a downhole end of the arrangement 10 (
FIGS. 1 , 2 and 5) is apin adapter tail 88 that features an orientation indicator such as agroove 90 that will always be in a position opposed to gravity when the arrangement is actuated because of the interaction betweenpin adapter 70 andweight assembly 50, which occurs attorque producer 58 ofassembly 50 and acomplementary profile 92 in this embodiment. The groove thus allows an operator to connect a tool at a specific desired orientation in the wellbore. One such tool is, as illustrated here, aperforation nozzle sub 94 havingnozzle receptacles 96. It will of course be understood that any tool could be attached to the pin adapter as desired or required for a particular application. - In operation, the
arrangement 10 is assembled at surface with atool 94 oriented to thegroove 90 so that the tool will have the ultimate desired orientation in the wellbore when the arrangement reaches a target depth and achieves the actuated position. The arrangement is then run in the hole until it reaches the target location. Pressure supplied to thepathway 20 acts upon the arrangement to urge a number of its components in the downhole direction. These are theseal sleeve 24, thespring compression mandrel 26 and theweight assembly 50. Thespring 34 is compressed byspring shoulder 30 of theseal sleeve 24 during this operation. Since gravity based orientation of theweight assembly 50 has already occurred, since it is continuous until engagement of the key 56 with thegear ring 72, downhole movement of the weight assembly causes the engagement of the key 56 between a pair of teeth of thegear ring 72. Since the gear ring itself is restricted in rotational movement by thepin 48, the weight assembly will now also be prevented from moving rotationally. It is noted that a reduction in pressure on thearrangement 10 will allow the key 56 to disengage from the gear ring and thereby restore rotational movement to the weight assembly under action of thespring 34 but too, a repressurization will reengage the key 56 with the gear ring. This can be repeated as desired. Importantly, and as noted above, the gear ring maintaining the weight assembly rotationless means that upon further pressure based downhole movement of the weight assembly and engagement of thetorque producer 58 with thepin adapter 70, all of the torque generated is transferred to thepin adapter 70. Torque on the order of about 70 ft lbs can be generated in one embodiment hereof upon the application of 5,000 psi. - While preferred embodiments have been shown and described, modifications and substitutions may be made thereto without departing from the spirit and scope of the invention. Accordingly, it is to be understood that the present invention has been described by way of illustrations and not limitation.
